Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The embodiment of the application provides a recording scheme of memory operation, and the scheme can record the memory operation in the application running process with finer granularity compared with the PSS. For ease of understanding, the terms referred to in this application are explained below.

1) Dynamic library

A dynamic library is a non-executable binary program file that allows programs to share code and other resources necessary to perform a particular task.

Dynamic libraries, also known as Dynamic Link Library (DLL), are one way to implement the concept of shared function libraries in operating systems.

Dynamic linking provides a way for a process to call functions that do not belong to its executable code. The executable code for the functions is located in a DLL file that contains one or more functions that have been compiled, linked and stored separately from the process in which they are used. DLLs also facilitate sharing of data and resources. Multiple applications can simultaneously access the contents of a single DLL copy in memory.

Updates can be more easily applied to individual modules using dynamically linked libraries without affecting other parts of the program. For example, with a large network game, if the code of a whole game of hundreds of MB or even several GB is put in an application, the modification work at a later date will be time consuming, and if the code of different functions is put in several dynamic link libraries, respectively, the update can be applied without regenerating or installing the whole program.

A dynamic link library file is a non-executable binary program file that allows programs to share code and other resources necessary to perform a particular task.

2) Hook function

The Hook (Hook) function is a technique for changing the result of an api execution by modifying the api function entry point to change its address to point to a new custom function.

The hook function is part of the message processing mechanism of the operating system, and by setting a hook, an application program can filter all messages and events at a system level and access messages which cannot be accessed under normal conditions. The essence of a hook is a program that handles system messages and is hooked into the system through a system call.

Referring to fig. 1, a system configuration diagram of an application development test system according to various embodiments of the present application is shown. As shown in fig. 1, the system includes an application development device 120 and an application execution device 140.

The application development device 120 is a computer device for a developer to develop an application program. For example, the application development device 120 may be a personal computer, a mobile workstation, or the like.

The application execution device 140 may be a computer device that executes an application developed by a developer. For example, the application execution device 140 may be a smart phone, a tablet computer, an e-book reader, smart glasses, a smart watch, an MP3 player (Moving Picture Experts Group Audio Layer III, mpeg Audio Layer 3), an MP4 player (Moving Picture Experts Group Audio Layer IV, mpeg Audio Layer 4), a laptop or a desktop computer, and so on. Alternatively, the application execution device 140 may also be referred to as a user device, a portable terminal, a laptop terminal, a desktop terminal, or the like.

The application development device 120 and the application execution device 140 may be connected by a wire. For example, the application development device 120 and the application execution device 140 may be connected via USB.

Alternatively, the application development device 120 and the application execution device 140 may be connected to each other via a communication network. Optionally, the communication network is a wired network or a wireless network.

Optionally, the wireless network or wired network described above uses standard communication techniques and/or protocols. The Network is typically the Internet, but may be any Network including, but not limited to, a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), a mobile, wireline or wireless Network, a private Network, or any combination of virtual private networks. In some embodiments, data exchanged over a network is represented using techniques and/or formats including Hypertext Mark-up Language (HTML), Extensible Markup Language (XML), and the like. All or some of the links may also be encrypted using conventional encryption techniques such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec). In other embodiments, custom and/or dedicated data communication techniques may also be used in place of, or in addition to, the data communication techniques described above.

Fig. 2 is a flowchart illustrating a method for recording memory operations of a dynamic library according to an exemplary embodiment, where the method for recording memory operations of a dynamic library can be used in a computer device running an application under test, such as the application running device 140 shown in fig. 1. As shown in fig. 2, the method for recording the memory operation of the dynamic library may include the following steps:

and step 21, responding to the call of the memory operation function in the running process of the application to be tested, and acquiring the called function address and the current memory operation information.

The memory operation function may be a function of allocating or releasing memory.

For example, the memory operation function may include at least one of the following functions:

Optionally, the memory operation information may include at least one of the following information:

memory size, target memory address, and identification of memory operation function.

And step 22, obtaining the identifier of the dynamic library initiating the call of the memory operation function at this time through the function address.

Step 23, writing the identifier of the dynamic library and the memory operation information into a memory operation log.

To sum up, according to the scheme shown in the embodiment of the present application, in the process of running the application to be tested, when the memory operation function of the computer device is called, the function address and the memory operation information are obtained, the identifier of the dynamic library initiating the call is obtained through the function address, and the identifier of the dynamic library and the memory operation information are written into the memory operation log together.

Fig. 3 is a flowchart illustrating a method for recording memory operations of a dynamic library according to an exemplary embodiment, where the method for recording memory operations of a dynamic library can be used in a computer device running an application under test, such as the application running device 140 shown in fig. 1. As shown in fig. 3, the method for recording the memory operation of the dynamic library may include the following steps:

step 301, intercepting the call of the memory operation function by the hook function in the running process of the application to be tested.

In this embodiment of the present application, in the running process of the application to be tested, when a certain dynamic library needs to perform a memory operation, for example, occupy or release a memory, a corresponding memory operation function may be called.

Correspondingly, the computer equipment can monitor the call of the memory operation function in the operation system through the Hook function, when a call event of the memory operation function occurs in the operation system, the call is directed to the self-defined function through the Hook function, and the self-defined function executes the steps of function address acquisition, function call and the like. The execution process of the custom function can refer to the subsequent steps.

Step 302, trace back the function call stack of the memory operation function to obtain the function address.

Optionally, the computer device may perform stack backtracking through an expansion operation, and store the function call stack obtained by backtracking as a first array; and extracts the elements in the first array as the function address.

The unfolding operation may be an unwind operation.

The execution of the program may be viewed as a continuous function call. When a function finishes executing, the program returns to the next instruction (immediately call instruction) of the call instruction to continue executing. The function call procedure is typically implemented using stacks, one call stack structure (call stack) for each user-mode process. The compiler uses the stack transfer function parameters, save return addresses, and temporarily save the original values of registers (i.e., the context of the function call) for recovery and storage of local variables.

The stack layout and function calling method of different processors and compilers may be different, but the basic concept of the stack is the same.

Function calls are usually nested, with multiple functions' information in the stack at the same time. Each function that does not complete a run occupies a separate contiguous area, called a Stack Frame (Stack Frame). A stack frame is a logical segment of a stack that is pushed onto the stack when a function is called and popped off the stack when a function returns. The stack frame stores function parameters, local variables, data required for restoring the previous stack frame, and the like.

The compiler makes use of stack frames to make the allocation and release of function parameters and local variables in the function transparent. Before the compiler hands over the control right to the function itself, a specific code is inserted to push the parameters of the function into the stack frame, and enough memory space is allocated for storing the local variables in the function. One benefit of using stack frames is that recursion is made possible because each recursive call to a function is assigned a new stack frame to the function, thus isolating the current call from the last call.

According to the scheme, the function call stack of the memory operation function is traced back through the unwind operation, so that the function address is obtained.

Step 303, executing the call to the memory operation function to obtain the memory operation information.

The computer equipment can call functions such as malloc, calloc, realloc, memalign, free and the like through memory allocation during hook running, replace the functions with self-defined functions, and use an unwind backtracking function call stack in the self-defined functions.

The self-defined function refers to a packaging function realized by a developer, for example, a malloc call is replaced by a self-defined myMalloc function, a rewind backtracking call stack is executed in the function, and then a real malloc function is executed.

For example:

the execution process of the custom function myMalloc () is as follows:

1) using a unwind backtracking stack, saving a function call stack into an array, wherein elements in the array are function addresses;

2) calling the real malloc to allocate the memory.

Typically, the call stack of an Advanced Reduced Instruction Set computer microprocessor (ARM) is expanded from a high address to a low address. In the ARM, a function call stack is increased from a high address to a low address, and when the function calls, PC, LR, IP and FP registers are respectively pushed into the stack, and then sp pointers are moved to open up stack space for the current program.

The meaning of the PC, LR, IP and FP registers is as follows:

PC, program counter. The instruction currently being run by the program is placed in the PC register.

IP, Instruction Pointer, used to control the execution sequence of instructions in the program.

FP, frame pointer. Usually pointing to the bottom of a stack frame of a function, indicating the starting position of a stack of functions.

LR, link register. When the function is called, the next instruction to be executed after the function is returned is put into the LR register, and the next instruction corresponds to the return address under the x86 architecture.

The call stack grows from a high address to a low address, when a function calls, the registers of PC, LR, IP and FP are respectively pressed into the stack, and then a stack top pointer (SP) is moved to open up stack space for the current program. Where SP points to the top position of the current stack space, which moves together when push and pop are performed.

In the embodiment of the application, the computer device may obtain a PC value of each layer of the function call stack through the Unwind _ Backtrace function, obtain an address of each layer of the function call stack, and obtain a dynamic library name where the function is located by dereferencing the function address through dladdr. Please refer to fig. 4, which shows a functional relationship diagram of a trace-back function call stack according to an embodiment of the present application.

And step 304, acquiring the identifier of the dynamic library initiating the call of the memory operation function at this time through the function address.

Optionally, the computer device may obtain the function by calling the address symbol to obtain symbol information of the function address; and obtaining the identification of the dynamic library from the symbol information.

Optionally, when obtaining the symbolic information of the function address by calling an address symbolic obtaining function, the computer device may convert the function address into an assigned data structure by calling the address symbolic obtaining function; the specified data structure is acquired as the symbol information.

Accordingly, upon obtaining the identification of the dynamic library from the symbolic information, the computer device may extract the target field in the specified data structure as the identification of the dynamic library.

Optionally, taking an example that an operating system of the computer device is an android system, the address sign obtaining function may be dladdr, where dladdr is a linux system call, and may convert a function address into a Dl _ info data structure. The computer equipment can analyze the function address in the function call stack through dladdr, then obtain the name of the dynamic library initiated by the function call through the dli _ fname field in the Dl _ info structure, and then obtain the identifier of the dynamic library.

In the linux system, when dlopen is called in a certain process to open a dynamic link library, a link of the process is correspondingly maintained, basic information such as address space of the name of the newly loaded dynamic library in the process is added, and then the symbol is updated. Therefore, as long as the link is traversed, the name of the dynamic library can be found out by knowing which item address the address of the searched function address is in, and then the relative address in the dynamic library is obtained by subtracting the starting address loaded by the process, which is the principle of dladdr. Therefore, by dladdr, the symbol name and the file where the symbol name is located can be resolved from the function pointer, that is, the dynamic library identifier is obtained by resolution.

Step 305, writing the identifier of the dynamic library and the memory operation information into a memory operation log.

Optionally, the memory operation information includes a memory size, a target memory address, and an identifier of the memory operation function.

When writing the identifier of the dynamic library and the memory operation information into a memory operation log, the computer device may store the memory size, the target memory address, the identifier of the memory operation function, and the identifier of the dynamic library as a log data in the memory operation log.

Please refer to fig. 5, which illustrates a data format diagram of a memory operation log according to an embodiment of the present application.

For example, as shown in FIG. 5, the first char byte represents which function of malloc, calloc, realloc, memalign, and free is used; the second int four bytes represents the allocated memory size; the third int four bytes represents the operation target memory address; the fourth int four bytes represent that the name of the dynamic library of the memory operation source is the second in the hook list. With the data structure shown in fig. 5, the log can be recorded only by 13 bytes in one memory operation.

Optionally, the memory operation information may further include other information, for example, time information of the memory operation may be further included.

Optionally, when writing the identifier of the dynamic library and the memory operation information into the memory operation log, the computer device may write the identifier of the dynamic library and the memory operation information into the memory operation log in response to the dynamic library being a designated dynamic library.

The development personnel can preset one or more appointed dynamic libraries, and when the memory analysis is carried out, the computer equipment can only record the memory operation logs of the appointed dynamic libraries, so that all memory operations are prevented from being recorded.

Optionally, before the called function address and the current memory operation information are taken, the computer device may display a dynamic library setting interface; the specified dynamic library is set in response to a setting operation in the dynamic library setting interface.

In this embodiment, the computer device may provide a setting interface of the specified dynamic library, so that a developer selects the specified dynamic library that needs to be recorded by the memory operation.

For example, please refer to fig. 6, which illustrates a schematic diagram of a dynamic library setting interface according to an embodiment of the present application. As shown in fig. 6, when setting a specific dynamic library, a developer may open a dynamic library setting interface 61, where the dynamic library setting interface includes setting options 62 of several dynamic libraries, for example, in fig. 6, setting options of dynamic libraries such as libuty.so, libmono.so, libpandora.so, and libgcloudhvoice.so, and the developer may select one or more specific dynamic libraries through each setting option 62, for example, the developer may set the setting options of one or more specific dynamic libraries to a checking state. After the setting, the computer device can set the selected designated dynamic library as a target dynamic library which is analyzed through the hook function channel, and the configuration code of the computer device can be as follows:

PlayerPrefs.SetString(“hkkoTarget”，“libunitty|libmono”)。

step 306, in response to the end of the running of the application to be tested, outputting the memory operation log to the target device.

Optionally, the computer device may output the memory operation log to the target device through a universal serial bus USB interface.

After the test case (i.e., the application under test) is run, a memory operation log file is formed on the computer device. The developer can pull the log file from the computer device to the local target device, and can automatically generate a memory audit test report of the dynamic library by using an analysis tool subsequently.

In another possible implementation manner, the computer device may also output the memory operation log to the target device through an internet address corresponding to the target device.

The computer device may also automatically send the memory operation log to the target device through the network after generating the memory operation log.

Optionally, before outputting the memory operation log to the target device through the internet address corresponding to the target device, the computer device may further display an address setting interface; and responding to the setting operation in the address setting interface, and setting the internet address corresponding to the target equipment.

In this embodiment of the present application, a developer may also set an internet address corresponding to the target device in an address setting interface provided by the computer device, so that after the computer device generates a memory operation log after the running of the application to be tested is finished, the memory operation log is automatically sent to the target device according to the internet address set by the developer.

In another possible implementation manner, the computer device may also send the generated memory operation log to the target device in real time, for example, after the computer device calls the memory operation function each time and generates a piece of log data, the generated log data is automatically sent to the target device.

Taking a computer application through a designated application program for performing memory operation recording, where the application to be tested is a game application as an example, before starting the application to be tested, a developer may set the following information in advance in the computer device through a setting interface of the designated application program: a specified dynamic library to be analyzed, an internet address of a log output, etc. Next, please refer to fig. 7, which illustrates a schematic diagram of memory operation records according to an embodiment of the present application. As shown in fig. 7, upon detecting the start of the game application by the specified application program, the configuration record configuration may be read, and first, it is determined whether the sample is required by the HOOK memory according to the record configuration (S71), if the sample is not required by the HOOK memory, ending, if the HOOK memory is needed to be sampled, further reading the configuration, obtaining the appointed dynamic library list needing HOOK (S72), executing HOOK according to the dynamic library list (S73), namely, the above steps 301 to 304, and a block of memory is mapped by mmap for storing the memory operation log (S74), and then when HOOK is applied to the memory operation initiated by the specified dynamic library, writing a piece of log data in the memory operation log (S75), determining whether the execution of the game application is finished, alternatively, the developer closes the designated application (S76), and if not, returns to S75, and if so, transmits the memory operation log to the target device (S77). Optionally, in another possible implementation manner, after the step S75, the computer device may also send the newly generated memory operation log to the target device in real time.

In addition, the scheme shown in the application does not need to keep the USB connection between the computer equipment and the target equipment all the time, and the stability is high.

In addition, the scheme shown in the application can be used for setting the required specified dynamic library by developers, can be customized according to the test requirement, and is high in flexibility.

In addition, according to the scheme shown in the embodiment of the application, the load of the acquired data is small, the influence on the running of the application to be tested is small, and the method can be suitable for the application with high requirements on running resources, so that the method has a large application range.

Taking the memory analysis of the game application program as an example, in the related art, the test group can only collect the whole PSS occupation of the game. When the memory occupation abnormally increases, the increase source module cannot be positioned. Through the scheme shown in the embodiment of the application, the test group can directly report the dynamic library name with the increased memory occupation, and the problem positioning and solving efficiency is greatly improved.

In addition, through the scheme, the abnormal behavior that a certain dynamic library continuously allocates the memory without releasing can be found, the memory leakage is found, and the dynamic library of the leakage source is positioned.
